Specification of Letters Patent.

Patented Oct. 29, 1912.

Application filed March 10, 1910. Serial No. 548,414.

To all whom it may concern Be it known that I, WILLIAM MONK, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Reversing Mechanism; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appert-ains to make and use the same, reference being had to the accompanying drawings, and to figures of reference marked thereon, which form a part of this specification.

This invention relates to an improvement in self-acting mules employed in the manu fact-ure of spool cotton, and particularly to a mechanism for operating the drum or tin roller which is employed in mules of this kind for operating the spindles by means of bands which pass around the drum and over the spindles, and as any one skilled in the art will readily understand.

In the reversal of mules it has been necessary in some types to remove each spindleoperating band from its pulley on the spindle, and twist the band or untwist it to secure reverse rotation, and in other types there are manually operated means for bringing about a reversal of the tin roller or drum, but these are usually complex and take up considerable room on the machine and add weight thereto.

My invention consists in providing a driving shaft, and also a shaft of the tin roller, with means for reversing the rotation of the drum, or tin roller, and its shaft, while the direction of the rotation of the drive shaft remains the same.

The invention is illustrated in the accompanying drawing, in which Figure 1 illustrates enough of a selfacting mule to show the location and operation of my invention. Fig. 2 is a section on line 2, 2, in Fig. 3, and Fig. 8 is a section on line 3, 3, in Fig.2.

I do not show a complete spinning-mule, but simply the frame 10 and the drive shaft 11 which is installed in all mules and is driven preferably by rope transmission acting on a grooved pulley 12 which is secured to the drive shaft 11 and is constantly rotating in one direction while the mule is in operation. Flanking the frame on either side are the usual tin rollers 13 which are termed in the trade tin rollers, but it will be understood that they can be made of any suitable material, and which drive, by means of suitable bands, the spindles, the spindles and bands not being illustrated in this application. It is the reversal of these drums 13 that the invention is designed to bring about, the drums being fastened to shafts 14, each shaft 14 being in line with the shaft 11, and I will now proceed to describe one of the connections, both of them being alike, and the description of one will suffice as a description of the other.

The mechanism consists of a bracket 15 which is shown in the drawing as secured to the frame, but it can be turned and its pedestal so constructed that it rests on the floor, the bracket 15 being merged into a receptacle or casing 16 which is provided, on its two ends, with bearings 17, one of these bearings receiving the drive shaft 11, and the other, the drum shaft 14. On the drive shaft 11 is secured a beveled gear 18, and on the drum shaft 14 is secured a beveled gear 19, the two shafts abutting between the gears, and when they are coupled they are bound together by a split ring 20 which is long enough to extend on each side of the abutting ends and is surrounded by a solid collar 21 in which is arranged a screw 22, and when the screw is screwed down tight, the screw, in conjunction with the solid collar, forces the split ring tightly around the shafts 11 and 14 so that they are bound to rotate in unison.

At right angles to the bearings 17, and about in line with the abutting ends of the shafts 11 and 14, is a bearing 23 in which is arranged to slide a shaft 24 which has a nut 25 on its end to limit the inward movement of the shaft 24, the shaft 24 being provided with a collar 26 and a head 27 between which is adapted to rotate a miter gear 29. The miter gear 29 is loose on the shaft, and the shaft 24 can move longitudinally through the bearing 23, and when the screw 22 of the coupling is tightened, and the shafts 11 and 14 work in unison, the shaft 24 is withdrawn so that the miter gear 29 is inoperative. A screw 30 in the bearing 23 acts to lock the shaft 24 in its adjusted positions. When the screw 22 of the coupling is unloosened, the coupling, that is, the split ring and the solid collar, can he slid from one side to the other, onto either one of the shafts, and fastened into place so as to prevent its traveling along the shafts unnecessarily, and the shaft 24: is forced forward after the screw has been unloosened, and the screw 30 is again tightened when the miter gear 29 is in mesh with the gears 18 and 19.

It will thus be seen that a simple and compact mechanism is provided for reversing the motion of the tin roller or drum of a self-acting mule, the screw 30 being always accessible, and the screw being easily reached when the cover 31 on the receptacle 16 is removed. The receptacle 16 and the cover 31, forming part of the bracket, also act to keep dirt from. the gears, and the receptacle 16 is also designed to hold oil so that the gears can touch it and thus insure their constant lubrication.

Having thus described my invention, what I claim is 1. A reversing gearing comprising a drive shaft and a driven shaft, with a bracket formed into a receptacle on its end, gears in the receptacle, the gears being in line on opposite sides of the receptacle to receive the ends of the drive shaft and driven shaft respectively, a split ring on the abutting ends of the two shafts, a solid collar surrounding the split ring, a screw passing through the solid collar and bearing on the split ring, a bearing on the-receptacle at right angles to the shafts, a sliding shaft in the last mentioned bearing, a miter gear on the end of the sliding shaft, and a screw passing through the right angled bearing to lock the shaft in its adjusted positions.

2. A reversing gearing comprising a drive shaft and a driven shaft, with a bracket formed into a receptacle on its end, gears in the receptacle, the gears being in line 011 opposite sides of the receptacle to receive the ends of the drive shaft and driven shaft respectively, a split ring on the abutting ends of the two shafts, a solid collar surrounding the split ring, a screw passing through the solid collar and bearing on the split ring, a bearing on the receptacle at right angles to the shafts, a sliding shaft in the last mentioned bearing, a miter gear on the end of the sliding shaft, a screw passing through the right angled bearing to lock the shaft in its adjusted positions, 1

and a cover on the receptacle for forming a casing for the reversing mechanism.

In testimony, that I claim the foregoing, l have hereunto set my hand this 9th day of March 1910.
